JESSE M. GARRETT, OF ST. LOUIS, MISSOURI.

BURNER.

App1ic:ation filed July 10, 1922. Serial No. 573,898.

To all whom it may concern:

Be it known that I, Jesse M. GARRETT, a citizen of the United States,residing at St. Louis, in the county of St. Louis and State of Missouri,have invented new and useful Improvements in Burners, of which thefollowing is a specification.

My present invention has reference to a liquid fuel burner forgenerating steam in lqorliilers or for heating stoves, furnaces or the.1 re.

My object'isto produce a burner in which 'the liquid fuel is mixed withsteam and forcibly ejected from the burner so that the same willbescattered around all'parts of the fire box.

A further object is to produce a liquid fuel burner in which the fueland steam are first conducted to a mixing chamber and find an outletthrough apertures therein and thereafter contact with the blades of aturbine to revolve the latter and to direct the mixed fuel against abaffle plate by which it is directed against all parts of the fire boxso that an even fiame'will be obtained in the entire surface of thefirebox and all fines connected therewith will be evenly heated.

The foregoing, and other objects which will present themselves as thenature of the invention is better understood, may be accomplished by aconstruction, combination and operative association of parts, such as isdisclosed by the drawings which accompany and which form part of thisapplication.

In the drawings I Figure 1 is a view of a fire box which is partlybrokenaway illustratingthe applica tion of the improvement therein.

FigureQ is asectional view on the line 2-2 of Figure 1, on an enlargedscale.

Figure 3 is a horizontal sectional view on the line 33 of Figure 2.Figure 4ris a similar sectional view on the line 4 ;t of Figure 2.

The remaining figures illustrate details.-

Referring now to the drawings in detail, F indicates a fire box for aboiler, furnace, stove or the like. Arranged in the fire box is a burnerconstructed in accordance with this invention.

The burnerincludes an upper and what I i ber in the nature of a turbinethereabove.

ing chamber 2 there isv a sleeve 10.

The mixing chamber is indicated by the numeral 3, the same having itsupper portion in the nature of a tubular member pro vided with exteriorthreads 2 and 3 and a partition 4. This partition is provided with anydesired number of circumferentially arranged preferably small openings5. The lower portion of the chamber 2 s rounded inwardly, beingsubstantially cone-shaped and terminating in a reduced neck 6 which isinteriorly threaded. Screwed in the neclr is a pipe 7, the pipeextendingthrough the bottom of the fire box. "The pipe 7 is n the nature of aconductor for the oil or other liquid fuel. through which the fuelenters.

The pipe 7 has a branch 5) The pipe '7 may have its bottom closed in'which event the same is provided with an opening for a jet pipe 9through which steam under pressure is conducted.

Screwed on the threaded end 3 of the m x The sleeve 10 is provided atitsupper end with an inwardly directed flange 11. The inner periphery ofthe flange 11 is round and the under face thereof is provided with acontinuous rounded concavitylQ. The upper edgeof the mixing chamber 2 isprovided with a-roundeddepression 13, the purpose of which arrangementwill be presently described.

There is preferably threaded on the mixing chamber a locking nut 12whereby the distance between the concavedshoulders 12 and 13 may beregulated.

The revoluble element which I have termed. the turbine is broadlyindicated by the numeral 1 1. This element includes a ring-likeperiphery 15that is approximately centrally formed with an outstandingflange 16, the flangebeing round in plan and the opposed faces of thesaid flange being coucaved. Between the concaved upper face of theflange 16 and the concaved inner face of the flange 11 there areanti-frictional balls 17, and between the concaved lower face of theflange 16 and the concavity in the upper end of the mixing chamber thereare simi lar anti-frictional balls 18. In this manner the member 14 maybe freely rotated. The member 14 is centrally formed with a tubu larportion 19 which is interiorly threaded,

and between the tube 19 and the ring 1:)

pipe 21. The pipe 21 is, of course, exteriorly threaded, and arrangedthereon there is a saucer-shaped bafile member 22, the same having itsopen face directed away from the burner 1. Screwed on the pipe and inc011- tact with the inner wall of the baffle 22 is a nut 23. Screwed onthe pipe 21 and in contact with the lower face of the baflie 22 there isa nut 24. The nuts23 and 241 hold the cupshaped baffle member properlyadjusted with respect to the turbine 1 The operation of the device maybe briefly I described as follows Steam and oil or other liquid fuel arelet in the mixing chamber through the pipe 7. This mixture escapesthrough the apertures 5 in the partition 4 in a thoroughly mixedcondition. The mixture contacts with the blades of the turbine andrevolving the eme om tho ugh y ehen e th e th mixtur is ea ly v periz d(a ter the fir as b s d), Wh n the sa e s del ve e in h vfire h F- Th les i" the erbin t nd to sp e t feel p a dly an outwardly with respect tothe burner, while the bafiie 23 directs the fuel laterally of the burnerin all directions so that every part of the fire box will receive fueland as this fuel is ignited, all parts of the fire box will be heated. Acertain quantity of the fuel will pass through the rather restrictedpassage in the pipe 21, and this fuel when ignited will be delivered ina straight line toward the top of the fire box.

It is believed that the foregoing description, when taken in connectionwith the drawings will fully set forth the construction and advantagesof the improvement to those skilled in the art to which such inventionsrelate, but it is to be understood that I am not to be restricted to theillustrated embodiment herein set forth, but may make such changestherefrom which may later suggest themselves, as fall within the scopeof what I claim.

Having described the invention, I claim:

1. In a liquid burner, a mixing chamber, a turbine therein, a bafflethereabove, means for delivering a liquid fuel separately through thebaffle and against the blades of the turbine to revolve the turbine tocause the ette to. d ec h eel g ine the virtue of contact therewith tobe scattered therefrom.

3. In a liquid fuel burner, a mixing chamer having an aperturedpartition therein, a turbine having angle blades thereabove,antiefrictional bearings between the mixing eh mhe n the tu bine e Pipeme be connected to and extending centrally from t r ine e l ttle membeadjust b e en t e p ne memb earl mea s te sheet ng e qu d u l under presure hreeeh th enertures of the partition to, cause said fuel to.

In testimony whereofI affix my signature.
